I agree with CecilbDemented about the catfight tactics and the European companies. You, however, have a great advantage over many of those production companies because of the language barrier. Most of the sites with the best action feature women who speak German, Spanish, Portuguese, or Japanese. Dialogue, believe it or not, is extremely important, especially at the end of the fight. The submission is the money shot and hearing the loser scream her submission and beg for mercy is the climax. These scenes are about the humiliation of losing to another woman, not about wrestling moves. Some post match humiliation (like face sitting) also adds to the appeal.
You also mentioned that your original idea was to emulate the action in the old apartment wrestling magazines. A large portion of this fan base are also fans of those magazines, as well as Cavalier and Nugget. Having a few girls with some pubic hair probably would not hurt being that so many of us are old school. This is one of the reasons I have not been back after my first couple of purchases. A little pubic hair pulling can go a long way toward attracting the most devout customers. This is also why I prefer well acted scripted fights. It is very difficult to convince models to do this for real, and in a real fight the opportunity does not always arise. Also the tap outs in real fights tend to be quick and sometimes silent. It is the humiliation, begging and taunting that we are after. To sum up - Nude, Humiliating, Bush, Catfight Tactics.
